Recommended Standard Designations

Electronic Industries Association (EIA) designations supersede Recommended

Standard (RS) designations. Reference to the old RS designations may appear

when depicting actual text (e.g., RS-232) as it may appear on the product rear

panels or on screens or pages in the Serial Remote or HTTP (Web Server)

Interfaces. All other references in the manual specify the EIA designations.

CAUTION

YOU SHOULD CAREFULLY REVIEW THE FOLLOWING INFORMATION.

Safety and Compliance

Electrical Safety and Compliance

The unit complies with the EN 60950 Safety of Information Technology

Equipment (Including Electrical Business Machines) safety standard.

The unit is rated for operation over the range 100 to 240 VAC. It has a maximum

power consumption of 88 watts, and draws a maximum of 770 mA.

Class I Pluggable Equipment Type A-Protective Earthing

The cable distribution system/telecommunication network of this product relies

on protective earthing. The integrity of the protective earthing must be ensured.

In Finland:

"Laite on liitettävä suojakoskettimilla varustettuun pistorasiaan."

In Norway:

“Apparatet må tilkoples jordet stikkontakt.”

In Sweden:

“Apparaten skall anslutas till jordat uttag.”

In Denmark:

"Apparatets stikprop skal tilsluttes en stikkontakt med jord, som giver

forbindelse til stikproppens jord."

Galvanic Isolator Use

In Norway:

“Utrustning som är kopplad till skyddsjord via jordat vägguttag och/eller via

annan utrustning och samtidigt är kopplad till kabel-TV nät kan i visa fall medfőra

risk főr brand. Főr att undvika detta skall vid anslutning av utrustningen till kabel-

TV nät galvanisk isolator finnas mellan utrustningen och kabel-TV nätet.”

Restricted Access Location

In Nordic Countries, equipotential bonding should be applied using the

permanently connected ground stud by a qualified service person.

Battery Warning

CAUTION

There is risk of explosion if you replace your battery with an incorrect

type. Dispose of used batteries according to the instructions.

Electrical Installation

CAUTION

Connect the ground stud, located on the modem rear panel, to a

power system that has separate ground, line, and neutral conductors.

Do not connect the unit without a direct connection to ground.

Chapter 4.2.3. Unit Ground Connection

Fusing

CAUTION

For continued operator safety, always replace the fuses with the

correct type and rating.

Chapter 4.2 Unit Connectors

CDM-710/L Broadcast Satellite Modem MN/CDM710.IOM

Preface Revision 12

xix

The unit is fitted with two fuses – one each for line and neutral connections.

They are contained inside a press-fit fuse holder that is part of the IEC power

module:

• Use T2.00A 20mm fuses for 115 and 230 volt AC operation.

• Use T6.25A 6.3 x 32mm fuses for 48 volt DC operation.

Operating Environment

CAUTION

Do not operate the unit in any of these extreme operating conditions:

• Ambient temperatures less than 0° C (32° F) or more than 50° C

(122° F).

• Precipitation, condensation, or humid atmospheres of more than

95% relative humidity.

• Unpressurized altitudes of more than 2000 metres (6561.7 feet).

• Excessive dust.

• Flammable gases.

• Corrosive or explosive atmospheres.

European Union Radio Equipment and Telecommunications

Terminal Equipment (R&TTE) Directive (1999/5/EC) and EN

301 489-1

Independent testing verifies that the unit complies with the European Union

R&TTE Directive, its reference to EN 301 489-1 (Electromagnetic compatibility

and Radio spectrum Matters [ERM]; ElectroMagnetic Compatibility [EMC]

standard for radio equipment and services, Part 1: Common technical

requirements), and the Declarations of Conformity for the applicable directives,

standards, and practices that follow:

European Union Electromagnetic Compatibility (EMC) Directive

(2004/108/EC)

• Emissions: EN 55022 Class B – Limits and Methods of Measurement of Radio

Interference Characteristics of Information Technology Equipment.

• Immunity: EN 55024 – Information Technology Equipment: Immunity

Characteristics, Limits, and Methods of Measurement.

• EN 61000-3-3 – Voltage Fluctuations and Flicker.

• Federal Communications Commission Federal Code of Regulation FCC Part

15, Subpart B.

CAUTION

Obey these instructions to make sure that the unit complies with the

standards:

• Use coaxial cable that is of good quality for connections to the

L-Band Type ‘N’ Rx (receive) female connector.

• Use Type 'D' connectors that have back-shells with continuous

metallic shielding.

• Type ‘D’ cabling must have a continuous outer shield (either

foil or braid, or both). The shield must be bonded to the back-

shell.

•

Operate the units with their covers on at all times.
